It will fit.
Why it is so hard to source.
First the price is super duper expensive, we don't dare to ship in a lot of units, scare it can't sell.

2ndly, sometimes it sells, but due to the scarce unit we bring in so you gotta wait for another batch.

Ooo, if he doesn't open it up we dont even know they are using grados magnet.

What I compare the AD series with the A series, they are sound differences between them. AD series as the name says it is the dynamic series, the air flow will improve the dynamics and will some how improve the separation, or pulls the soundstage further. Good for music that has more than 10 types of instrument playing.
As for me I prefer the A series (Audiophile series). It has more accurate positioning and more details to obtain. So to speak, more refined.
